摘要

Conservation agriculture plays a crucial role in sustainable agricultural systems, emphasizing the preservation of soil health, biodiversity, and natural resources. Implementing conservation tillage and strip intercropping is a forward-thinking strategy designed to optimize soil organic carbon sequestration, enhancing soil health, particularly in semi-arid regions. To examine the benefits of reduced tillage and legume-based strip intercropping on soil carbon fractions and sequestration. An experimental setup using a randomized complete block design was initiated. The main treatments were conventional tillage (CT), minimum tillage (MT), and reduced tillage (RT), with sub-treatments of sole cropping (wheat, chickpea, sesame, soybean) and strip intercropping (wheat-chickpea, sesame-soybean). The RT outperformed other tillage treatments in all carbon fractions. The total organic carbon (TOC) concentration was higher in sole chickpea (1.65 g kg−1) and wheat-chickpea strip intercropping (1.64 g kg−1) during the first season, and in sole soybean (1.68 g kg−1) and sesame-soybean strip intercropping (1.67 g kg−1) at 0–15 cm soil depth. RT with leguminous crops, both as sole and strip intercropping, showed greater soil carbon sequestration (up to 2.03 Mg ha−1 yr−1) compared to cereals. These findings suggest that farmers can not only boost the health of their soils but also contribute to mitigating climate change through enhanced soil carbon sequestration by adopting such sustainable agricultural practices.
